Zusammenfassung:An injectable composition of the present invention has remarkably increased safety by forming, into a composition, a sorbitan unsaturated fatty acid ester having a polar head with two or more -OH (hydroxyl) groups, is in a liquid phase in a phase where an aqueous fluid is absent so as to be easily applied to pharmaceutical preparations in dosage forms, and forms a liquid crystal in an aqueous fluid phase so that sustained-release effects of GnRH derivatives, which are used as a pharmaceutically active ingredient in vivo, are exhibited. In addition, in an injectable composition of the present invention, a sustained-release lipid pre-concentrate comprising GnRH derivatives includes water, and thus a liquid injectable agent forms a liquid crystal gel immediately after administration, so that the effects of reducing initial release rate and remarkably increasing sustained-release properties of the drug are exhibited.
